CHARLES WALKER; OF KNOXVILLE, TENNESSEE,

TURNING-PLUG.

Specification of Letters Patent.

Patented May 20, 1913.

Application filed January 17, 1912. Serial No. 671,707.

T 0 all whom/2'15 may concern:

Be it known that 1, CHARLES WALKER, a citizen of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented new and useful Improvements in Turning-Plugs, of which the following is a specification.

This invention relates to improvements in turning plugs and it proposes a construction wherein the movement of the valve body is suitably limited, for example, to an arc of ninety degrees, but wherein the direction of movement may be readily and quickly varied, to conveniently conform to environments.

The invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a side elevation of a valve in which the features of the present inven tion are incorporated; Fig. 2 is a section on the line AA of Fig. 1, showing the parts set for a clockwise movement of the valve body for one change of relation; Fig. 3 is a similar view, but showing the parts set for a counter-clockwise movement of the valve body for the same change of relation.

Similar characters of reference designate corresponding parts throughout the several views.

The valve casing 1 may be of ordinary form and incloses a valve body 2 which is rotatable through a suitable range, e. g. an arc of ninety degrees. A cap 3 fits closely over the upper end of the casing 1, being held in relation thereto by the valve handle 1, the inner squared end of which extends downwardly, passing through a central opening in the cap 3 and engaging in the square recess of a boss 5 which is provided upon the upper face of the valve body. The casing 1 has a suitably located stop lug 6 which projects from its upper edge and cooperates with a stop lug 7 which is carried by the cap 3. The combined length of the lugs 6 and 7 depends upon the degree of movement which the valve body is to be allowed to have. As shown, the lugs 6 and 7 have a combined extent of 270 degrees, the valve being movable through an extent of ninety degrees. The lug 6 is relatively fixed, while the lug 7 is relatively adjustable to a position at either side of the lug 6. The lug 7 fits against the inner peripheral face of the cap 3 and is held in position by .a screw 8 which is threaded laterally through said cap and passes also through the boss 5 to engage in a recess in the inwardly extended end of the handle 4. The screw 8 not only secures the lug 7, but serves also to bind together the handle 4; and the cap 3. In the construction shown in Figs. 1 to 3, the lug 7 rests upon the upper edge face of the casing 1 and is spaced sufficiently from the top wall of said cap to enable said lug to be turned about the screw 8 as an axis, when the cap is removed from the casing. Thus, the lug 7 may be disposed at either side of the lug 6, it being only necessary for this purpose to remove the cap, and the movement of the valve body is in accordance with the position which the lug 7 bears in a particular relation of said body to the lug 6.

In Fig. 2, the lug 7 is shown as positioned immediately at the right of the lug 6, and in Fig. 3 the lug 7 is shown as positioned immediately at the left of the lug 6. In both of these figures, the valve handle points in the same direction, and it is to be assumed that the valve body is in the same, (2. 9., closed, position. With the parts related as shown in Fig. 2, the movement of the valve body to open position is clockwise, as indicated by the arrow, and to closed position, is counter-clockwise. lVith the parts related as shown in Fig. 3, the movement of the valve body to open position is counter-clockwise, as indicated by the arrow, and to closed position, is clockwise. In either case, the movement of the valve body is limited to an arc of ninety degrees.

The improved valve herein described may have any internal construction or special features desired, and by virtue of the features referred to, may be readily adapted to environments for which turning plugs of ordinary construction will not serve.

Having fully described my invention, I claim:

A valve of the type set forth, comprising a casing having a fixed stop lug at the upper end thereof, a rotary valve body in the casing, a cap fitting over the upper end of the casing and inclosing the fixed stop lug, a handle having an end which projects through the cap and engages in the valve body, a stop lug associated with the cap and forming acompanion of the fixed stop lug, the second-named stop lug being 10 the second-named stop lug being positioned at either side of the fixed stop lug by a turn ing movement about the screw as an axis.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit nesses.

CHARLES XVALKER.
